Away team risk a long shot (7,6)
I believe the answer is:
outside chance
'a long shot' is the definition.
(thesaurus)
'away team risk' is the wordplay.
'away' becomes 'out' (similar in meaning).
'team' becomes 'side' (both can mean a sports team).
'risk' becomes 'chance' (synonyms).
'out'+'side'+'chance'='OUTSIDE CHANCE'
(Other definitions for outside chance that I've seen before include "It might just happen" , "one at long odds" , "smallest likelihood" .)
